Hereinafter, the carry out DL TDD dynamic configurations and UL of embodiment according to the present invention are described respectively with reference to figure 1 and Fig. 2-6
The solution of HARQ sequential during TDD dynamic configurations.
DL HARQ sequential
Fig. 1, which is shown, carries out DL TDD dynamics in the base station in TDD eIMTA systems of embodiment according to the present invention
The schematic diagram of the method 100 of configuration.
First, DL reference configurations are used as in any one of step 110, base station selected TDD configurations 0-6.In method 100
In, base station can select any one of 7 kinds of TDD Configuration Types shown in above-mentioned table 1, and 2 and 5 are configured rather than just TDD,
As DL reference configurations.
In step 120, for selected DL reference configurations, base station determines the Candidate Set reconfigured available for PDSCH
It closes.The candidate collection so that in DL TDD Dynamic Configuration Process the TDD configurations of base station can only be included by the candidate collection
Change between TDD configurations, i.e. the TDD configurations of base station can only be selected from the candidate collection.
In one implementation, the UL subframe position of each TDD configurations in the candidate collection, which at least covers the DL and refers to, matches somebody with somebody
The UL subframe position put.
For example, when selecting TDD with setting to 0 as DL reference configurations, be located at the 2nd since TDD matches somebody with somebody the UL subframe that sets to 0,3,4,
7th, in 8,9 subframes, and in TDD configurations 0-6 only TDD match somebody with somebody the UL subframe position that sets to 0 can cover the 2nd, 3,4,7,8,9 subframes,
Therefore candidate collection is only matched somebody with somebody including TDD and is set to 0 determined by.
For another example, when selecting TDD configurations 1 as DL reference configurations, since the UL subframe of TDD configurations 1 is located at the 2nd, 3,7,8
In subframe, and TDD configuration 0-6 in only TDD with set to 0, TDD configure 1 and TDD configuration 6 (its UL subframe be located at the 2nd, 3,4,7,8
In subframe) UL subframe position can cover the 2nd, 3,7,8 subframes, therefore identified candidate collection include TDD with set to 0, TDD
Configure 1 and TDD configurations 6.
For another example, when selecting TDD configurations 2 as DL reference configurations, since the UL subframe of TDD configurations 2 is located at the 2nd, 7 subframes
On, and TDD configuration 0-6 in only TDD match somebody with somebody set to 0, TDD configuration 1, TDD configure 2 and TDD configuration 6 UL subframe position can cover
2nd, 7 subframes, thus identified candidate collection include TDD with set to 0, TDD configuration 1, TDD configure 2 and TDD configuration 6.
Similar, in the case of each TDD is configured as DL reference configurations, it can determine corresponding candidate collection.
Table 2 below lists TDD configure 0-6 as DL reference configurations when and can be used for PDSCH the candidate collection reconfigured it
Between correspondence.
The correspondence of table 2DL reference configurations and candidate collection
Correspondence shown in table 2 can prestore in a base station so that base station can it is more convenient really
Determine candidate collection.
Next, in step 130, base station is notified selected DL reference configurations to UE by RRC signaling, so that
During DL TDD dynamic configurations, UE always performs DL HARQ procedures according to the sequential of the DL reference configurations.
Application way 100, base station can determine the scope of DL TDD dynamic configurations to carry out dynamic configuration in the range,
And pass through cycle longer high-rise RRC signaling and notify DL reference configurations so that UE can be total during Dynamic Configuration Process to UE
It is to perform DL HARQ procedures according to the sequential of the DL reference configurations.
UL HAR sequential
For UL HARQ sequential, it is contemplated that for TDD with setting to 0 for 6, HARQ round trip delay times (RTT) are not equal to
10ms, so as to which PUSCH retransmission delay maximums are up to 70ms or 60ms.For example, Fig. 2 show TDD be configured to configuration 5 when
The schematic diagram of HARQ RTT.As shown in Figure 2, when SIB1 is configured to TDD with setting to 0, and actual TDD is configured to configuration 5,
PUSCH retransmission delays will be up to 70ms.
Therefore, in the present invention, for UL HARQ sequential, it is proposed that SIB1 is configured to TDD configurations 1-5.
Based on this suggestion, below according to whether supporting TDD with setting to 0 with 6 for reconfiguring and whether allow in SIB1
DL subframe change into UL subframe, propose following 4 kinds for determining the concrete schemes of UL HARQ sequential.

Change between TDD configurations, i.e. the TDD configurations of base station can only be selected from the candidate collection.
In one implementation, the DL subframe position of each TDD configurations in the candidate collection, which at least covers the UL and refers to, matches somebody with somebody
The DL subframe position put.When configuring 1-5 as UL reference configurations table 3 below illustrates TDD and it can be used for the re-matching of PUSCH
Correspondence between the candidate collection put.
The correspondence of table 3UL reference configurations and candidate collection
Next, in step 330, the sequential of SIB1 configurations is deferred to perform UL HARQ procedures in base station.
As can be seen that in this scheme, the candidate collections of UL TDD dynamic configurations does not include TDD with setting to 0 with 6, from
And limit its degree of freedom reconfigured.
In order to support TDD matches somebody with somebody to set to 0 to be used to reconfigure with 6, it is proposed that the following method 400-600.
What Fig. 4 showed embodiment according to the present invention carries out UL TDD dynamics in a base station in TDD eIMTA systems
The schematic diagram of the second method 400 of configuration.
In method 400, SIB1 configurations are fixed as TDD configurations 1, and the DL subframe in SIB1 is allowed to change into UL
Frame.That is, in SIB1 (situation of Pcell) and RadioResourceConHgCommonSCell IE (situation of SCell) by with
UL subframe can be changed by being set to the subframe of DL subframe.It, can be by by flexible sub-frame (subframe for not supporting the UE of eIMTA
3rd, 4,7,8,9) in DL subframe be configured to multicast/multicast single-frequency network (MBSFN) subframe solve radio link monitoring (RLM)/
Wireless resource management (RRM) problem, and support the UL of the UE of eIMTA is transmitted can be performed on data area (on TDD UL-
The problem of backward compatibility in DL eIMTA, can refer to the applicant in submit, Application No. on January 18th, 2013
201310020284.6 application for a patent for invention).
First, UL reference configurations are used as in any one of step 410, base station selected TDD configurations 1-5.
In step 420, for selected UL reference configurations, base station determines the Candidate Set reconfigured available for PUSCH
It closes.The candidate collection so that in UL TDD Dynamic Configuration Process the TDD configurations of base station can only be included by the candidate collection
Change between TDD configurations, i.e. the TDD configurations of base station can only be selected from the candidate collection.
In one implementation, the DL subframe position of each TDD configurations in the candidate collection, which at least covers the UL and refers to, matches somebody with somebody
The DL subframe position put.Following table 4 lists the re-matching with can be used for PUSCH when TDD configures 1-5 as UL reference configurations
Correspondence between the candidate collection put.
The correspondence of table 4UL reference configurations and candidate collection
Next, in step 430, the sequential of SIB1 configurations is deferred to perform UL HARQ procedures in base station, and works as Candidate Set
Conjunction includes TDD with setting to 0 or when 6, when the UL HARQ sequential of subframe 4 and 9 defers to TDD and configures the HARQ of subframe 3 and 8 in 1 respectively
Sequence, and the HARQ procedure ID of subframe 4 and 9 is identical with the HARQ procedure ID of the subframe 3 and 8 in TDD configurations 1 respectively.
Fig. 7 is shown when UL HARQ sequential defers to SIB1 and TDD is allowed to match somebody with somebody the subframe 4 when setting to 0 with 6 for reconfiguring
With the schematic diagram of 9 HARQ sequential.
As can be seen that in this scheme, compared with method 300, the candidate collection of UL TDD dynamic configurations is matched somebody with somebody including TDD
It sets to 0 with 6 when TDD configurations 1 (UL reference configurations for), so as to which the degree of freedom reconfigured improves.According to this method, all UL subframes
HARQ RTT be 10ms.
What Fig. 5 showed embodiment according to the present invention carries out UL TDD dynamics in a base station in TDD eIMTA systems
The schematic diagram of the third method 500 of configuration.Method 500 can regard the compromise of method 300 and 400 as.
When without using specific RRC signaling, the relation of UL reference configurations and candidate collection is as shown in table 2 above, UL
HARQ sequential defers to SIB1 configurations;
When indicating that UL reference configurations are used as in TDD configurations 6 by RRC signaling, UL HARQ sequential defers to TDD configurations 6, waits
Selected works are combined into { 1,2,3,4,5,6 };
When by RRC signaling indicate TDD with set to 0 be used as UL reference configurations when, UL HARQ sequential defers to TDD with setting to 0, and waits
Selected works are combined into { 0,1,2,3,4,5,6 }.
In method 500, SIB1 configurations can be any one of TDD configurations 1-5, and allow the DL subframe in SIB1
UL subframe is changed into, UL reference configurations can be any one of TDD configurations 0-6.
First, UL reference configurations are used as in any one of step 510, base station selected TDD configurations 0-6.
In step 520, for selected UL reference configurations, base station determines the Candidate Set reconfigured available for PUSCH
It closes.The candidate collection so that in UL TDD Dynamic Configuration Process the TDD configurations of base station can only be included by the candidate collection
Change between TDD configurations, i.e. the TDD configurations of base station can only be selected from the candidate collection.
In one implementation, the DL subframe position of each TDD configurations in the candidate collection, which at least covers the UL and refers to, matches somebody with somebody
The DL subframe position put.
Next, in step 530, judge whether selected UL reference configurations are TDD with setting to 0 or 6.
If the judging result of step 530 is no, method 500 proceeds to step 540, base station defer to SIB1 configurations when
Sequence performs UL HARQ procedures.In this case, corresponding candidate collection and obtained 4 phase of table in above method 400
Together.
If the judging result of step 530 is yes, method 500 proceeds to step 550, indicates to use by RRC signaling
